I have one too... Owl Drug Stores with Triad tubes advertised. Problem is that these are 100% useless except for nostalgia. They do not usually test dynamic mutual conductance. Just an arbitrary "Good/Fair/Bad" scale. But they are RARE nowadays, so I hate to see one junked. If you want to test tubes, you need a nice Hickok or B&K Mutual Conductance machine.
I vote to have it saved, but don't pay much if you can help it.
